This PAS-C01 practice question tests your understanding of technology. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is migrating its SAP ERP system from on-premises to AWS. The migration involves a heterogeneous database migration from Oracle to SAP HANA. Which AWS service should be used to perform the database migration with minimal downtime?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Database Migration Service (AWS DMS) with a heterogeneous migration using the SAP HANA target endpoint
Option D is correct because AWS DMS supports heterogeneous migrations from Oracle to SAP HANA using the SAP HANA target endpoint. Option A (SCT) is used for schema conversion, not data migration. Option B (Server Migration Service) is for server migrations, not databases. Option C (Database Migration Service) is the correct service but Option D specifies it correctly.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
AWS Schema Conversion Tool (AWS SCT)
Why it's wrong here
SCT helps convert the database schema but does not perform the data migration.
✗
AWS Server Migration Service (SMS)
Why it's wrong here
SMS migrates entire servers as images, not suitable for database schema and data conversion.
✓
AWS Database Migration Service (AWS DMS) with a heterogeneous migration using the SAP HANA target endpoint
Why this is correct
DMS supports heterogeneous migrations using the SAP HANA endpoint, allowing schema and data conversion with minimal downtime.
Related concept
Standard ACLs match source addresses.
✗
AWS Database Migration Service (AWS DMS) with a homogeneous migration
Why it's wrong here
Homogeneous migration is for same database engine; Oracle to HANA is heterogeneous.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
Standard ACLs match source addresses.
Extended ACLs can match source, destination, protocol and ports.
The first matching ACL entry is used.
There is usually an implicit deny at the end.
TExam Day Tips
→Check inbound versus outbound direction.
→Read the ACL from top to bottom.
→Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related PAS-C01 ACL questions on filtering logic and placement.
